Thermal insulation
Beaker in a beaker — which packing keeps the water hot?
In the gap:
Rate
Steady
Stopwatch
00:00
Temperature
20.0 °C
Water in
0 / 150 cm³
Now try an insulating material
3D paused — this device reclaimed the graphics memory.
It will come back on its own in a moment. Nothing has been lost.
Now try another material
Which material keeps the water hot for longest?
After this practical you will be able to:
  1. 1Measure how fast the water cools.
  2. 2Compare materials fairly.
  3. 3Explain which one keeps heat in best.
Smaller drop = better insulator
